Background
The soil surface micro-topography processing technology is used for processing a plurality of micro-pit arrays on the surface of field soil so as to change the micro-topography of the surface of the field and further block the field surface runoff generated by rainfall. Through the land preparation measure, surface runoff can be collected and infiltrated into the soil, so that water and soil loss caused by excessive rainfall is effectively controlled, rainwater is converted into soil water, and water is enriched on the surface of the ground for growth and utilization of crops. The technology adopts the modes of regulation, temporary storage and accumulation utilization on runoff, finally turns harm into benefit, plays a positive role in crop growth while reducing the negative influence of excessive rainfall on agricultural production, improves the utilization efficiency of natural rainfall to the maximum extent, and achieves the dual aims of controlling water and soil loss and relieving drought and water shortage.

When the convex tooth compacting machine is used for processing the micro-topography of the soil surface in the areas, if the soil firmness is higher, when the micro-pit water storage device works under the condition of smaller vertical load, the micro-pit water storage capacity is reduced to about 100 ml at least, effective water storage is difficult to realize, therefore, the micro-topography processing operation on the soil surface can be effectively realized by a larger vertical load, although the ballast force vertically applied to the soil by the convex tooth ballast is increased, the convex teeth can overcome the hard soil surface and press micro pits on the ground surface, the water storage capacity of the micro-pits is improved to a certain extent, however, the higher the soil firmness is, the greater the compaction force which needs to be increased is, the hardening degree of the soil is aggravated by the excessively increased compaction force, and the formed soil surface moisture is difficult to permeate into the soil, so that the formed soil condition is not suitable for cultivation.
